Thanks for the reply.
I don't think the solutions in the videos apply to what I'm trying to accomplish. First, I am not trying to customize by aircraft. I only have one aircraft, the M30T. Second, I do not want to replace or customize an exisiting service type, I want to create an additional one.
For example, instead of only having Basic Battery and Full Battery service types, I would like add a new one, Maintain Battery. Doing so would result is three battery service types - Maintain Battery, Basic Battery, and Full Battery. The idea is for Maintain Battery to trigger reminders to conduct certain maintenance, such as checking the battery charge status and recharging, based on x days since Mantain Battery was last performed.
For further background, this is a small public safety agency with minimal deployments. Unfortunately, batteries have been left unattended for many months, causing the potential for damage. I am trying to avoid this happening again, and would like a service trigger reminding my pilots to check the batteries and maintain their charge.
